"Steampunk is a sci-fi genre based on an alternate universe in which technology advanced along mechanical lines, not digital as we have today. It generally refers to a culture with technology powered by steam, often with dark, grim and dystopian themes.
Steampunk is derived from the fashion and technology of the Victorian era, but frequently includes aspects from other eras and cultures such as the wild west cowboys and swashbuckling pirates. Steampunk fashion uses accessories and attention to detail that conveys the use of technology through mechanical means."
